You’ve by now seen those pictures of Arnold Schwarzenegger on the set of “Terminator Salvation” having a jocular conversation with star Christian Bale. What we all know is… what’s he doing there? Is he just having lunch? Are they retelling Batman tales to one another?

Well, seems Schwarzenegger has joined the cast of the film!

Latino Review has the low-down : “The premise of Arnie’s involvement is to have a fully rendered digital face of Arnie replacing the recently cast Roland Kickinger (The Younger version of Arnie). It seems the Director Mc G will in no doubt try all he can to ensure the Governator has some sort of involvement and as a result Arnold was on set providing key ADR (Voice over) for the visual effects guys to reference during post production.”

How cool is that? Now I imagine Arnie will only appear briefly – probably towards the end of the film somewhere – but it’s something.
